Installing Fabric

Regular installation

MultiMC

NOTE MultiMC is a modding-friendly alternate launcher for Minecraft, which is recommended for working with Fabric and can be found here. If you don't wish to use MultiMC or don't know or care what launcher you're using, follow through to the regular client instructions.

  1. Create a new game instance.
  2. Select “Edit Instance” in the instance context menu or on the right side of the window.
  3. On the Version tab of the configuration window, click “Install Fabric” to bring up a dialog with all the available Fabric Loader versions. Pick one and click OK to add it to the instance.
    • Generally using the latest available Loader version is recommended.
    • The loader should be mostly game version-independent. If this situation changes, it will be pointed out, so don't worry!
  4. Press OK. Your Fabric instance is ready to go - feel free to add mods to it!

Mojang's Minecraft Launcher

  1. Download the Fabric installer from the download page.
  2. Open the installer. In the window you need to configure the mapping and loader version (as per advice in the MultiMC section) and the install location (the default should be fine on most platforms).
    NOTE You need to enable snapshots in order to make the installer show mapping options for Minecraft snapshots.
  3. Press Install. A new game version and profile will be created in the launcher's menu, which you can now use to launch Fabric.

Server

NOTE Up-to-date as of Loader 0.4.4+. Older versions choose different techniques. Installer 0.4.0+ required!

  1. Download the Fabric installer from the download page.
  2. Open the installer. Select the “Server” tab at the top of the window.
  3. In the window you need to configure the mapping and loader version and the install location.
    NOTE You need to enable snapshots in order to make the installer show mapping options for Minecraft snapshots.
  4. Press Install. In the output directory, a fabric-server-launch.jar will be created. It expects a server.jar, which is the vanilla server JAR, generally found on Mojang's version announcement blog posts, next to it, but will also generate a properties file on first launch where you can change the path.
    NOTE If you are upgrading your existing server, remember to remove the .fabric folder if the installer did not remove that for you! Or you will get classloading errors.
